Mathlib is the source of the theorem; the local Lean replay and page review are separate.

Evidence boundary

Exact formal statement only

This target indexes Mathlib's complex Fréchet-differentiable normed-space theorem: E and F are complex normed spaces, f is differentiable on all of E, and its range is bounded. The conclusion is exact equality with a constant function. The declaration is more general than the scalar ℂ→ℂ slogan and does not require F to be complete.
